The transition to renewable energy is a cornerstone of achieving the United Nations Sustainable Development Goals (SDGs), particularly SDG 7, which focuses on providing affordable and clean energy for all. As the world’s population grows and economies expand, the demand for energy has surged, placing immense pressure on the environment and contributing to climate change. The reliance on fossil fuels, which account for a significant portion of global greenhouse gas emissions, underscores the urgent need for a shift towards sustainable energy solutions. This article explores the importance of renewable energy in addressing global challenges, backed by facts, statistics, and real-world examples.
The global energy challenge
Global energy consumption continues to rise, driven by population growth, urbanisation, and technological advancements. According to the International Energy Agency (IEA), global energy demand increased by 4% in 2021, recovering from the pandemic-induced decline. However, nearly 759 million people worldwide still lack access to electricity, highlighting the disparities in energy distribution.
Fossil fuels remain the primary source of energy, contributing to 73% of global CO2 emissions. This heavy reliance exacerbates environmental degradation, accelerates global warming, and hinders the progress of achieving sustainability. Transitioning to renewable energy sources such as solar, wind, hydro, and geothermal power is essential to mitigate these challenges and ensure economic equality.
Moreover, energy insecurity impacts vulnerable populations disproportionately. In sub-Saharan Africa, over 600 million people live without access to electricity, which impedes education, healthcare, and economic opportunities. Women and children are often the most affected, as they rely on polluting and inefficient energy sources like kerosene and firewood. Addressing these disparities is critical for achieving gender equality and fostering inclusive development.
Renewable energy offers numerous advantages over traditional fossil fuels. It is environmentally friendly, reduces carbon emissions, and provides a sustainable alternative to finite resources. Studies indicate that increasing the share of renewable energy to 50% of global energy production by 2030 could reduce greenhouse gas emissions by over 30%, significantly contributing to climate action.
Technological advancements in renewable energy have made it more accessible and cost-effective. The cost of solar photovoltaic (PV) systems, for instance, has dropped by 82% over the past decade. Similarly, wind energy capacity has increased tenfold since 2000, driven by innovations in turbine technology. These developments not only promote environmental protection but also enhance energy security and economic growth.
In addition to environmental benefits, renewable energy fosters economic equality by creating millions of jobs globally. The renewable energy sector employed 12.7 million people in 2022, according to the International Renewable Energy Agency (IRENA). This figure is expected to grow significantly as governments and private sectors invest in green energy projects.
Several organisations and nations have demonstrated the potential of renewable energy in achieving the global goals.
· Germany has become a leader in renewable energy, with renewables accounting for 46% of its electricity consumption in 2022. Through policies like the Renewable Energy Sources Act, Germany has invested in wind and solar energy while phasing out coal.
· The International Solar Alliance (ISA), a coalition of 121 countries, aims to promote solar energy deployment worldwide. By 2030, ISA targets 1,000 GW of solar energy capacity, which could mitigate over 1 billion tonnes of CO2 emissions annually.
· In rural Kenya, the non-profit M-KOPA provides affordable solar energy solutions to low-income households. Since 2012, it has connected over 3 million homes to solar power, enhancing quality of life and reducing dependence on kerosene.
· The Green Climate Fund supports renewable energy projects in developing nations, such as a wind farm in Senegal that will power 2 million homes. These projects illustrate how international collaboration can drive meaningful change.
The global society and collaboration
The transition to renewable energy requires collective action and a commitment to justice and strong institutions. The global society plays a pivotal role in fostering international cooperation, sharing technological innovations, and ensuring equitable energy distribution. Collaborative frameworks like the Paris Agreement underscore the importance of unity in addressing climate action.
Moreover, achieving economic equality through renewable energy investments can empower developing nations. By prioritising green infrastructure and inclusive policies, countries can drive sustainable economic growth while addressing social disparities. Partnerships between governments, private sectors, and non-profits are essential to overcoming barriers and accelerating progress.
The role of education and public awareness cannot be overstated. Promoting renewable energy literacy and supporting research and development are vital for inspiring innovation and driving adoption. Universities, think tanks, and grassroots organisations have a significant part to play in this global effort.
Looking ahead
The future of renewable energy is promising yet challenging. While the cost of renewable technologies continues to decline, the abundance of inexpensive fossil fuels poses a significant obstacle. Addressing this requires strong policy measures, public awareness, and investment in science and innovation. By 2050, renewable energy could account for 90% of the world's electricity needs, according to the International Renewable Energy Agency (IRENA).
Innovative technologies such as energy storage systems, smart grids, and hydrogen fuel cells are expected to revolutionise the energy landscape. These advancements can improve efficiency, reduce costs, and support the integration of renewable sources into existing energy systems. The role of the global society in promoting these technologies will be critical.
Achieving the sustainable development goals hinges on the widespread adoption of renewable energy. As a key driver of environmental protection, economic equality, and social justice, renewable energy represents a pathway to a more sustainable and equitable future. Continued efforts, global collaboration, and innovative solutions are imperative to meet the energy demands of tomorrow while safeguarding the planet for future generations.
